Gtk::ColorSelection*  wrap (GtkColorSelection* object, bool take_copy=false) Detailed Description A widget used to select a color. This widget is used to select a color. It consists of a color wheel and number of sliders and entry boxes for color parameters such as hue, saturation, value, red, green, blue, and opacity. It is found on the standard color selection dialog box Gtk::ColorSelectionDialog.

Gdk::Color Gtk::ColorSelection::get_current_color (   )  const bool Gtk::ColorSelection::get_has_opacity_control (   )  const   Determines whether the colorsel has an opacity control. Returns: true if the colorsel has an opacity control. false if it does't. bool Gtk::ColorSelection::get_has_palette (   )  const   Determines whether the color selector has a color palette. Returns: true if the selector has a palette. false if it hasn't. guint16 Gtk::ColorSelection::get_previous_alpha (   )  const   Returns the previous alpha value.

The first time this is called, it will also set the original opacity to be alpha too. Parameters: alpha  An integer between 0 and 65535. void Gtk::ColorSelection::set_current_color ( const Gdk::Color&    color )    Sets the current color to be color . The first time this is called, it will also set the original color to be color too. Parameters: color  A Gdk::Color to set the current color with. void Gtk::ColorSelection::set_has_opacity_control ( bool    has_opacity = true )    Sets the colorsel to use or not use opacity. Parameters: has_opacity  true if colorsel can set the opacity, false otherwise. void Gtk::ColorSelection::set_has_palette ( bool    has_palette = true )    Shows and hides the palette based upon the value of has_palette . Parameters: has_palette  true if palette is to be visible, false otherwise. void Gtk::ColorSelection::set_previous_alpha ( guint16    alpha )    Sets the 'previous' alpha to be alpha . This function should be called with some hesitations, as it might seem confusing to have that alpha change. Parameters: alpha  An integer between 0 and 65535. void Gtk::ColorSelection::set_previous_color ( const Gdk::Color&    color )    Sets the 'previous' color to be color . This function should be called with some hesitations, as it might seem confusing to have that color change. Calling set_current_color() will also set this color the first time it is called. Parameters: color  A Gdk::Color to set the previous color with.
